Philippa York (previously known as Robert Millar; born 13 September 1958) is a Scottish journalist and former professional road racing cyclist.
Competing as Robert Millar, York has been one of Britain's most successful cyclists of all time. She won the "King of the Mountains" competition in the 1984 Tour de France and finished fourth overall. York was the first rider from an English speaking country to have won the Mountains classification in the Tour de France. This success was the first time a British rider won a major Tour classification, and was unsurpassed as the highest Tour finish for a Briton for over 20 years until Bradley Wiggins was retrospectively placed third in the 2009 Tour de France. She rode the Tour de France eleven times, completing the race eight times.
York also achieved the highest finish by a Briton in the Giro d'Italia, finishing second in 1987 and also winning the King of the Mountains classification. As well as the Giro second-place finish, she finished second in two other Grand Tours: the 1985 and 1986 Vuelta a España.). Her second place at the 1985 Vuelta came after losing the leader's jersey on the penultimate stage, in what is widely thought to be collusion by the Spanish-speaking teams. Further victories came at the 1985 Volta a Catalunya, the 1989 Tour of Britain and the 1990 Dauphiné Libéré.
After retiring, York moved into journalism, as well as spending a year as a coach for British Cycling. She reduced her public commitments in 2000 following hostile stories regarding rumours of her gender transition, and after an appearance as Millar at the 2002 Commonwealth Games left public life altogether. In the 2010s, having transitioned to living as York, she returned to journalism, publishing under the name of Robert Millar until a decision to appear on TV commentary led to her revealing her transition publicly in 2017.
